\begin{abstract}
In the past two decades the Internet grew from a small scientific network to a worldwide communication platform where almost everyone is able to participate. 
Furthermore, in recent years the Internet gained more and more popularity due to the so called Web 2.0. The ongoing miniaturization and integration of computer and communication technologies results in nearly everything in our daily life containing some kind of computer. Thus, in the following years the Internet will grow from an Internet of computers to an Internet of Things. However, with the connection of almost every ``thing'', a lot of problems and technological challenges arise. 

This paper introduces the basic concepts of the Internet of Things (IoT). Furthermore, the commonly used and most promising technologies which are currently used in the IoT are presented. Since the IoT is not yet realized completely, the future challenges in the context of this topic are worked out and possible solutions are presented.
